Cytoplasmic inheritance is due to

Options

A. Plastids
B. Mithochondria
C. Cytoplasmic particles
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Cytoplasmic Inheritance:**
- Cytoplasmic inheritance, also known as extra-chromosomal inheritance, refers to the transmission of genetic material that occurs outside the nucleus. This involves genes that are located in organelles such as mitochondria and plastids (like chloroplasts).

2. **Identifying the Organelles Involved:**
- The key organelles associated with cytoplasmic inheritance are:
- **Mitochondria:** These organelles have their own set of genes and are primarily inherited maternally. This means that the mitochondrial genes are passed down from the mother to the offspring.
- **Plastids (Chloroplasts):** Similar to mitochondria, chloroplasts also contain their own genetic material and can contribute to inheritance.
- **Cytoplasmic Particles:** Other cytoplasmic elements, such as kappa particles, can also play a role in inheritance.

3. **Evaluating the Options:**
- The question provides the following options:
- A. Plastids
- B. Mitochondria
- C. Cytoplasmic particles
- D. All of the above
- Since all the mentioned organelles and particles contribute to cytoplasmic inheritance, the correct answer is "All of the above."

4. **Conclusion:**
- Therefore, cytoplasmic inheritance is due to plastids, mitochondria, and cytoplasmic particles, making the correct answer **D. All of the above**.
